IMPROVEMENT IN BALlNG-PRESSES.

Specification forming part of Letters Patent No. 39,158, datcd'July 7, 1863.

To all whom it may concern.-

Beit known that I, D. L. MILLER, of Madison, in the county of Morris and State of New Jersey, have invented-a new and Improved Press for Compressing Hay, Cotton, and other Articles for Baling; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a plan or top view of my invention; Fig. 2, a back View of the same; Fig. 3, a side view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in operating the follower of the press by means of right and left screws formed on a driving-shaft and gearing in worm-wheels which are fitted on shafts placed at the ends of the press-box, said shafts being provided with conical pulleys to receive the chains or ropes which draw up the follower, and the driving-shaft being fitted in adjustable bearings, all being arranged in such a manner as to admit of the desired work being rapidly done and in an efficient or proper manner.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the press-boX, which may be of the ordinary rectangular form and slotted at each side to admit of the ends of the followerbar B passing through, to have the cords or chains C attached to them. There is a door, D, at each side of the press-box A at its upper p'art, and there is also a door, E, at the top of the press-box. These doors may be provided with fastenings arranged in the usual or in any other proper way.

At each end of the press-box, at its upper part, there is a horizontal shaft, F. These shafts are fitted in suitable bearings, a, which are attached to the press-box A, and on each shaft F there is a cone, G, which has a spiral groove, I), made in it. (See Fig. 3.)

To the cones G there are attached the ropes or chains C, one to each, and said ropes or chainsare attached to the ends of the followerbar B, as previously referred to.

On the shaft there are also placed wormwheels H H, one on each shaft, and into these wheels H screws I I gear, said screws being on a shaft, J, the bearings c of which are in the upper ends of rods K K, the lower ends of which are tted on cranks d at the ends of a shaft, L, the latter having its bearings e attached to the press-box A. rIhe shaft J passes through two plates, f f, which have each a pin, g, projecting from them, said pins passing through oblong slots h in the plates of the bearings a. These pins g serve as guides for the shaft J, to insure of it being moved or adjusted in avertical plane. The screws I I have not their pitch in the same direction-one is a right and the other a left hand one, as shown clearly in Figs. 1 and 2.

At eachend of the shaft J there is a handwheel or radial arms, M, by which said shaft is turned when operated manually. N is a handle or small lever, which is attached to the shaft L.

The operation is as follows: The press-box A is supplied with a requisite quantity of the material to be compressed, the follower of course being down or at the lower part of the press-box A; The doors at the upper part of the press are then all closed and fastened and power applied to the shaft J, the screws I I of which rotate the shafts F F through the medium of the worm-wheels H H. As the shafts rotate, the ropes or chains C are wound up on the cones G, and the follower consequently elevated. The follower will be quickly moved at first, as the ropes or chains are attached to the larger ends of the cones, and the speed of the follower gradually decreases as it rises, and the power of course proportionately increases in consequence of the ropes or chains being wound upon the gradually-decreasing dialneter of the concs G. When the substance within the press-box is sufficiently compressed, it is bound and discharged from the press-box as usual, and the operator or attendant, by turning the shaft L by means of the handle N, will throw up the rodsK K, and the screws I I will be free from the worm-wheels H H, as shown in Fig. 2 in black and in Fig. 3 in red. As soon as the screws I I are elevated above the wheels H H, the follower will descend by its own gravity to the bottom of the press-box and be in position for a succeeding operation, the shaft J being lowered, so that the screws I I will gear into the worm-wheels H H.

Having thus described my invention, what I claim as new, and desire to secure by Letters Fatent, is-

l. The ropes or chains C and the cones G L, substantially as shown, for the purpose of G on the shafts F F, in combination with the throwing the screws I I in and out of gear with driving-shaft; J,Wor1n-Whee1s H H, and screws the Wheels H H, as herein specified. r

I I, all arranged substantially as and for the D. L. MILLER. purpose herein set forth. Vitnesses:

2. Having the drivngshaft J tted in rods M. S. PARTRIDGE, K K, which are Connected to cranks on a shaft, J. W. COoMBs. l
